Chess rating test
What is my chess rating? One game can't really tell you, but it can give you a first idea. Play a bot, and see roughly what level that game looked like.
This is a rough guide from one game, on a hand-tuned curve. It is not a real rating, and weaker bots give a noisier result.
How much do you play?
How the estimate works
- Your answer picks a bot to play. There is no clock, and you can take moves back.
- The bot's engine scores the position before each of its moves, which shows how much your last move cost.
- We average that cost over your moves and read an approximate number off a curve we tuned by hand.
- You see a Level from 1 to 10, the approximate number, and the bot closest to it to play next.
You need at least 6 graded moves to get an estimate. Moves you take back are left out.
What this test can't tell you
- It is one game. That is far too little to measure a player.
- It is hand-tuned. The curve was not fitted to rated players' games.
- It is not a real rating. No federation or chess site recognises it.
- Weaker bots are noisier. They search less deeply, so they grade your moves less reliably.
Treat the result as a friendly starting point for choosing your next opponent, and nothing more.
Questions people ask
- Is this my real chess rating?
- No. A real rating comes from many rated games against other players. This is a rough guide from one game against a bot, on a curve we tuned by hand.
- Can I compare this number with a FIDE, Chess.com or Lichess rating?
- No. It has not been checked against any of them, so please do not treat it as a conversion.
- Why might my result change from game to game?
- One game is a small sample. A good or bad day, a short game or a single blunder can move the number a lot.
- Why do weaker bots give a noisier result?
- Weaker bots look fewer moves ahead, so they judge your moves less reliably. A result from a game against Pip says less than one from a game against a stronger bot.
- Is my result saved?
- No. The estimate appears at the end of the game and is not stored. Like any game against a bot here, the win, loss or draw counts towards your journey in your own browser.
